/*
How to use:

ajax.x - The XMLHttpRequest object (or MS equivalent) used for communication

ajax.serialize(f)
f = the form element you wish to be serialized
This function serializes all the fields in a form so that they can be passed as a query string in the form "arg1=val1&arg2=val2".

ajax.get(url, func)
url = the url to query (can contain arguments after a '?')
func = the function to call once the response is returned
This function uses a GET request to query the specified url and return a response to the specified function.

ajax.gets(url)
url = the url to query (can contain arguments after a '?')
This function uses a GET request to query the specified url and return a response synchronously. Use this sparingly, as synchronous calls can lock up the browser.

ajax.post(url, func, args)
url = the url to query
func = the function to call once the response is returned
args = a string containing arguments to be passed to the url
This function uses a POST request to query the specified url and return a response to the specified function.

ajax.update(url, elm)
url = the url to query
elm = the (name of the) element to update
This function uses a GET request to query the specified url and insert the result into the specified element.

ajax.submit(url, elm, frm)
url = the url to query
elm = the (name of the) element to update
frm = the form element to submit
This function is typically used in the onsubmit handler of a function. The form is not submitted the usual way; the form is instead serialized using "ajax.serialize" and submitted using "ajax.post". The result is then inserted into the specified element.
